King County, WA Cities and unincorporated areas

King County, Washington
  • Added 19 Sep 2018

This layer is a compilation of city jurisdictional information from three counties: King, Pierce and Snohomish, plus the unincorporated areas in each of the three counties. Uses the best available information from each of the 3 counties to produce the composite product for the jurisdictional areas and assumes the areas outside of the jurisdictions to be unincorporated. Updated whenever changes are made to any one of the source data sets. For King County this will be whenever CITY_AREA (parent is CITY_ANNEX) is updated to Spatial Data Warehouse. Pierce and Snohomish updates are shared with King County on quarterly to semi-annual basis. Updates are made so that the King County portion of this composite is synchronous with the information in the master King County jurisdiction layer.

This layer is a component of Administrative Areas.

These administrative layers represent incorporated areas, zip codes for King, Snohomish and Pierce counties and tribal lands.
